Application tiled January 26, 1912. Serial No. 673,594.

To all whom t may concern;

Be it known that I, Nits NILsoN, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Non-Refillable Bottle, of which the following is a specification.

The principal objects of this invention are to provide a non-refillable bottle of exceedingly simple construction so that it shall be capable of being manufactured in large quantities or small at a comparatively low expense, and especially to provide a construction which shall be sanitary, neat, and clean, and in which al1 the parts except one cork-packing shall be of transparent glass so that its cleanliness will be readily obvious; and to provide a construction which cannot be refilled without breaking the seals and destroying them, and one which can be applied entirely within the neck of the bottle so that a clumsy and large neck will not have to be provided nor any projection therefrom.

Reference is to be had to the accompanying drawings, in which- Figure 1 is a central vertical sectional view of one form of the invention; Fig. 2 is a sectional view of the same on the line 2-2 of Fig. 1; and Fig. 3 is a view similar to Fig. 1 showing another way in which the invention can be carried out.

In the form shown in Figs. 1 and 2, the bottle a is provided with a circular protuberance 10 near the bottom of the neck and projecting inwardly all around the same. On this rests a glass cylinder 11 fitting loosely in the neck of the bottle and having an inwardly extending projection 12 constituting a Hat shelf on the top. This cylinder projects up above this shelf to a considerabledistance, and is provided with a cylindrical chamber 13 above the shelf. In this chamber is located a square valve 14 also of glass, preferably, and having a fiat lower face adapted to cover the opening 15 in the center of the piece 11. This square valve is designed to fit within the cylindrical chamber 13 so that its edges just clear the walls thereof, so that it will not have any material sidewise play, but will be free at all times to move up and down. From a consideration of Fig. 2 it will be seen that passages are provided at the flat sides of this valve for the How of liquid. At the top cork or stopper 19 if desired. @ver the whole thing is placed a metallic seal 20 having a private seal or stamp 21 on the top which is designed to be the same as the label or seal 22 on the side of the bottle.

In Fig. 3 the same principles are shown, but a passage 25 corresponding to the passage 15 is formed between the walls 26 of an integral projection extending inwardly from the neck of the bottle itself so that the element 11 in Fig. 1 is simply made integral with the rest of the bottle. The other elements are the same.

In using the device in either form, the bottle is filled, then the removable elements which have been described are introduced. After they are introduced the bot-tlc can be opened by breaking the seal 20 which, of course, destroys it. Then the stopper 19 can be removed and the bot-tle emptied readily. If it is desired to refill the bott-le it will be obvious that the valve 14 will be forced to its seat and prevent the refilling in any ordinary way.

The principal points to which attention is called are the exceeding simplicity of the device and cheapness of manufacture, the sanitary qualities, t-he fact that'it contains no parts likely to get filled with material or likely to contain any sediment or dirt in the use of the device, as practically all the parts are transparent, so that this fact can be observed readily,.also the presence of the two seals, one on the side and the other on the top which will show whether the bottle has been tampered with.

While I have illustrated and described two preferred embodiments of the invention, I am aware that many modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claim. Therefore I do not wish to be limited to all the details of construction herein shown and described, but j What I do claim is As an article of manufacture, a bottle having an integral circular projection near the bottom of the neck, a stationary cylin smaller in diameter than the outside dimensions O f sa@ w1ve,

In testimony whereof I have hereunto set my hand,in the presence of two subscrib ing Witnesses.

drical piece loosely fitting in the neck of the bottle and resting on said projection and having a restricted conical passage therein and an enlarged cylindrical chamber above 5 said passage having a circular flat seat at the bottom thereof, a square valve in said chamber having a flat bottom for closing said passage and having spaced legs projecting up therefrom, and a stopper at the top Yof 10 the bottle having a passage therethrough= NILS NILSON.
